碩士 === 中正理工學院 === 電子工程研究所 === 88 === The objective of this thesis is implementation of a sensorless speed controller of vector control induction motor based on TI DSP (digital signal processor), fixed point TMS320C50, due to strong arithmetic ability, computing speed, 10KW buit-in SRAM, low cost and popular application. The original arithmetic structure of TMS320C50 chip is 16 bits. For good computing precision and reducing error, the arithmetic operation is designed with in interger 16 bits and decimal 16 bits, completed 32 bits arithmetic structure of close loop induction motor speed control. We adopted (modify model reference adaptive system; MMRAS) speed controller to compare the performance of PI speed controller. Besides, we intend to develop a sensorless controller based on the (model-reference adaptive system; MRAS) estimation to estimate rotor speed to research objective. Finally, experimental results of MMRAS speed controller have better response and ability with or without load than that of PI speed controller. However, results of sensorless speed controller for induction motor vector control are not good enough but prove the effectiveness of the design.
